Logic & Math
How to play Regex Hunter
Each hunt gives you two lists: targets your pattern must catch, and innocents it must spare. Type a regex, watch the words light up as they match, and refine it until every target is caught and every innocent is safe. Your score is the length of your pattern, so once it works, the real puzzle begins: trimming it down one character at a time.
- The pattern c.t catches all three targets and spares every innocent in just three characters. Real hunts get much harder, and you'll reach for character classes, anchors, alternation and lookarounds.
